stormy weather

It was a wild night and a massive amount of rain has fallen. The river has burst its banks and the fields are flooded.
The ground is sodden, even though it's been dry through the autumn the ground is still saturated from the summer of rain. The poor chickens are paddling.
The rain stopped for a while and we walked the dogs at Owenahincha. The sea and sky were dramatic.

I was pleased with this shot, and a few others, but am gutted to find the same dark blob in the right of the shot in all of them, and I am not sure how to properly go about cleaning this camera
